of which the follovvlng is a Specification.

The principal object of the present invention is to provide a car journal roller bearing.- which shall be elicient, durable and capable of satisfactory operation under conditions of use in street and other railway Another object of the present infor convenient inspecservice. vention 1s to provlde tion, assembly and taking apart and repairy of the bearing.

The invention will be claimed at the'end hereof, but will be first described in connection with the embodiment selected from other .embodiments of it for purposesv of illustration in the accompanying drawings, in whichi Figure 1, is a side view principally in section of a roller bearing embodying features of the invention. v

Fig. 2, a 'face view of the end thrust drawn to a'somewhat enlarged scale, and

Fig. 3, is an end viewpartly in section of thecap- In the-drawings 1 is the axle or journal and 2, is the housing or box. These may `conform to the requirements of. standard Master Car Builders trucks. fitted to the axle or journal and 4 is a sleeve fitted to the housing or box. These sleeves may be properly hardened and betv'veen` them is` `l arranged an annular series of rollers 5 adapted to take the radial thrust. 6', is a dust guard arranged at the rear of the box. 7, is a cover applied to the engd of the box and shown as removable by means of the screws 8, so as to. permit of the insertion of the sleeve 4 and rollers 5. 9, are flanges which complete the roller race. 10, is a cap 'detachably arranged to .close an 3, is a Sleevef opening in the cover- 7; as shown the opening and the cap are threaded. The cap is provided with a headed post 11 upon which are mounted hard washers or plates 12 and 13 withfthe end thrust ring 14 interposed between them so that' the two plates 12 and n 18 with the interposed member 14 constitute an end thrust for the bearing Which is revmovable and transportable with the cap 10 and which is adjusted by the adjustment of the cap 10. The cap 10 is shown as provided with acavity 15 adapted for the application of a key or wrench-with a groove 16 communicating with the cavity andfwith radial notches 17. 18, is a coiled wire having a projecting end 19. When the cap is screwed to its proper position'the coil of the wire, being in thel groove 16,' projects the end 19 into a notch 2O in the cover, thus holdingthe cap against accidental displacement. The`var1ous notches 17 can be made to receive the projecting end 19 of the wire 18 so that the end 19 i ject from anyv of the notches 17 as may be required by cap 10.

What I claim is: f In a rollerbearing the combination of an axle, a housing open at its end, an end cover for the housing having an opening thereinv opposite the end of the axle, av cap having screw-and-thread connection with the opening in the end cover, ing means carried by the cap for locking the cap against turning ,movement in' either A ldirection and4 1n respect to the housing, a

postsecured to the cap and extending toward the end of the axle, and an anti-friction end-thrust bearing carried by the post,

substantially as described.

Intestimony whereof I have hereunto signed my name.
